Question juridique clé
Whether the appellant was procedurally precluded from challenging the deduction of fixed costs because it had not requested a post-calculation/expert supplement.
Solution extraite
No; the record showed the appellant had sufficiently challenged the deduction of fixed costs and requested clarification of the cost breakdown.
Motifs extraits
The cantonal court's finding that no relevant request had been made was irreconcilable with the file and with the appellant's explicit objection to deducting fixed costs from gross revenue.
